Fig. 16 is a transverse section of still another' jembodiment showing a fixture composed of a plurality of strips with reflecting means disposed to intercept light'rays where thestrips are spaced from one another.

In the embodiment illustrated in Figs. 1 and- 2, there is shown a wall bracket l to which is connected a lamp 2, said wall bracket I having the arms H to which isconnected the vertically extending shell 3 to conceal the lamp 2. The

outer face of the shell 3 is preferably provided"4o with an ornamental effect either due to, the configuration of the shell itself or to the ornamental matter secured thereto, Fig. 2 showing ornamental matter 4 secured to the outer face of I the shell 3 in the present instance to form an arrangement of raised and receding surfaces to intercept indirect light rays reflected by reflect- "the .shell 3 to intercept direct rays from they I lamp 2 with certain of its reflecting surfaces deflecting the light rays so received onto other reflecting surfaces all within the strips 5 which in turn deflect such received light rays onto the outer face of the shell 3.

From the foregoing, it will appear that the channels or channeled strips 5 are used to bring the light rays from the lamp 2 around the edges 6 onto the outer face of the shell 3.

For securing the channeled strips 5 in place in the present instance, there are provided two blocks 1 and 8 adjacent the lower end of the shell 3 and two blocks 9 and I9 adjacent the upper end of the shell 3, which blocks are slotted to receive the end portions or edges 6 of the shell 3 and which blocks are also provided with outer faces conforming to the inner channeled surfaces of the strips 5 to snugly fit in the strips 5.

Preferably these blocks 1, 8, 9 and I0 are composed of a translucent substance or plastic material, such as Catalin to cooperate with the light rays of the lamp 2 to enhance the lighting effect according to the design which it is desired to produce.

The shell 3 itself is preferably channeled or trough shaped to house the lamp 2 and conceal it from view. While the shell 3 is shown in the embodiments of Figs. 1 and 2 as intended for use with a wall fixture, it may be spaced from the floor of the room in which it is located. It may of course also be supported on the floor as is the case with the vertically extending shell H in the embodiment illustrated in Fig. 3.

In the embodiment illustrated in Fig. 3, the shell H is sectional, the shell II being made sectional to facilitate manufacture with a design of the type there illustrated. The composite shell ll there likewise is channeled or trough shaped to house a lamp or source of light or row of lamps l2 and I3 and in the present instance is composed of two end sections l4 and I5, two intermediate sections I6, I! and a peak section I 8.

The sections l4 and i5 as shown are connected to the intermediate sections l6 and I! respectively by the bayonet joints l9 and the sections l6 and l! in turn are connected to the section [8 by the bayonet joints 2!). The sections l6 and H in the present instance are provided with screw-threaded bosses 22 in alinement with openings in the flanges of the concave alzac reflecting shell 23 and also in alinement with openings in the ends of the arms 24 and 25 of the bracket 26 extending from the wall 21. There are provided many brackets 26 as desired depending upon the height of the shell I I.

Secured to the reflecting shell 23 and extending inwardly therefrom, there are provided the tubes or conduits 28 to the inner ends of which are secured the sockets 29 for the lamps l2 and l The electrical conductors from the lamps l2 and i3 as shown in Fig. 4 extend from the sockets 29 out through the conduits 28 and then over and along the outer grooves 30 of the arms 24 and 25.

The upper edge of the shell may of course terminate in any ornamental design desired, preferably of course to correspond with the motif on the outer face of the shell ll. With a design, such as shown in Fig. 1, an intermediate round portion 3|" may be preferred and with a design, such as shown in Fig. 3, probably the extension of the peak motif there shown may be preferred.

Along the lateral vertically extending edges of the shell H, there are arranged the reflecting means, in the present instance consisting of the strips 32 and 33 which may be connected to the shell H by any suitable means. In the present instance, screws 34 are shown extending from the inner overlapping portions of the strips 32 and 33 to the inner face of the outer edge formations 35. The strips 32 and 33 are preferably spaced from the edge formations 35 by the spacing collars 36 through which the screws 34 extend.

The number of lamps l2, I3 required for a shell ii will of course depend upon the length of the same and upon the type of lamp used. In the embodiment illustrated in Fig. 3, there are shown two lamps of the standard filament type in which the axes of the sockets 29 extend vertically. The shells H in the present instance depend for their ornamentation upon the shape of the shell reflected in the outer appearance on the outer face of the same and also upon the particular surface finish provided. As an instance, the outer surfaces of the sections l4 and 55 have a plurality of projecting edges 31, the intermediate sections l6 and H a plurality of projecting edges 38 and the section H! a plurality of projecting edges 39. These edges 37, 38 and 39 preferably have a smooth or plain finish as distinguished from a serrated or a saw tooth finish. The edges 31 in the present instance are the ends of smooth finished depressions 40 and 4! which are located within the path of light rays deflected by the inner faces of the reflectors or strips 32 and 33. The edges 38 on the other hand are narrow smooth finished strips at the ends of intervening recesses 42 and 43 which have a serrated or saw tooth finish in cross-section, see Figs. 4 and 5.

The crests of the saw teeth characterizing the surface finish of the depressions 42 and 43 are parallel with the edges 38 to resemble a very finely ribbed surface. The depressions between successive teeth approximate one sixty-fourth of an inch in depth. Preferably the portion of the sections l4 and I5 adjacent the sections l6 and I! are also recessed to form the concave recesses 44 which are also preferably provided with a serrated or saw tooth finish, such as the surface finish of the recesses 42 and 43.

The edges 39 as shown in Fig. 4 are preferably formed at the ends of ledges 45, 46 and 41. As indicated in Fig. 4, it will be apparent that at least the edges 31, 38 and 39 are in the path of the li ht rays deflected by the reflectors or strips 32 and 33. of the saw tooth finish of the surfaces 44, 42 and 43 will lie in the path of the light rays deflected by the reflectors or strips 32 and 33. The result will be that highly illuminated narrow stripes will be formed by the edges 31, 38 and 39. Surfaces of different light intensities and that will have different high light areas according to the location of the observer will be formed by the surfaces 44, 42 and 43 and dark areas formed between the sections [6, I! and the ledges 45 and by the recesses formed between the ledges 45 and 46 and by the recesses formed between the ledges 46 and 41.

It is of course apparent that the serrated line defining the surfaces 44, 42 and 43 is not intended to portray the actual depth of a recess between successive saw teeth or successive ribs but rather merely to typify that these surfaces are not smooth and plane but serrated or saw tooth in cross-section.

It will also appear that certain faces The reflector 23 of course is provided mainly to reflect the light rays from the lamps I2 and I3 against the wall 21. In addition to the re-v flector 23, there are in the present instance provided. twoadditional reflector shells 48 and- 49 which are secured in the present instance to the inner faces of the sections I4 and I5 respectively' Each reflector shell 48, 49 has a substantially plane portion 59 extending from an edge portion i flectors 48, 49 are preferably secured to the sections I4, I5 respectively by screws, such as the screw 52, in the present instance connecting'the curved portion 5I -to a section I4, I5 adjacent its bayonet joint I9.

In the embodiment illustrated in Fig.6, there is shown a channeled shell 53 similar to the shell, I! but extending horizontal as an instance from one pillar- 54 to another/not shown. In this embodiment, the shell 53 is shown as composed of three sections, two sections 55 and 55 substantially identical to one another in place of the sections I4, I6 and I5, I1 respectively, and a third section 51 in place of the section I8. Here each section 55, 55 has only two smooth finished stripes 58 and 59.defining the intervening edges by the three concave successive depressions. 60, 7 5| and 62, each of which has a surface finish that is preferably serrated, or saw tooth in cross section, such as the saw tooth surface of the recesses 44, 42 and 43 of Fig. 4.

The section 51 is preferably connected to the sections 55 and 55 by bayonet joints 63 and 64 similar to the bayonet joints 20 and otherwise substantially, identical in shape and surface fin ish to that of the section I8 in Fig. 4.

Along the longitudinal outer edge portions 65 and 65, there are provided the channeled reflecting strips 5'! and '58, similar to the reflecting strips 32, 33 of the embodiment shown in Fig. 4 and also positioned to interceptdirect light rays from a lamp- 59 or similar lamp source mounted inside of the shell 53, and deflect them onto other surfaces within the channels 61 and 68 in turn to be deflected onto the outer faces of the shell 53 again to produce a plurality of brightly i1- luminated stripes with intervening dark areas and light changing areas, such as those produced by the serrated surfaces 60, BI and 62.

The light source may be mounted within the shell 53 in any suitableway, in the present instance, if lamps such as the standard-filament lamps are used by connecting the lamps B9 to sockets I0 connected to projections II, 12 extending inwardly from the inner faces of the sections 55, 55. In some instances, the shell 53 may of course be solely supported at its ends by pillars such as the pillar 54. On the other hand, as illustrated in the embodiment of Figs. 7 and 8,

such a shell, as an instance the shell 13 maybe pillars, such as the pillar 54, other supporting 83 is connected between the ends of the arms 11, I8 and the projections 19, 80, respectively. In this embodiment, similarly, the sections 8| and 82 are provided with bentreflecting means 84, such as the shells 48, 49 illustrated in the embodiment of Fig. 4. I

In this embodiment the ends of the shell-"I3 may be closed asparticularly indicated in Fig. 7

by rounding the sections 8|, 82 into one another The reflecting strips A10 .85 and 85 along theouter edge portions of the at the ends of the shell 13.

sections 8I, 82 are similarly rounded into one another as indicated at 81. For the purpose of finish, the edges 83 of the section 89 are also rounded into one another at one end of the shell I3 as at 90.

As distinguished from the embodiment illustrated in Fig. 6 in which the reflecting strips 61 and 58 may be supported at their ends by the means will have tobe provided in the embodiment of Fig. 8 for the reflecting strips 85, 95.

These reflecting'strips 85, 05 may here also be connected to the outer ends of the sections 8 and 82 by the screws SI. r 1

.Any number of other ways may of course be provided for closing the ends of the shells 13 depending upon the ornamental finish required. In the embodiment of Fig. 9 as aninstance, it

is shown how a plurality of these shells 13 may go be connected together to form an angle with one anotherin turn to form a completely enclosed polygonally shaped shell or only part of a polygon as when connected to a pillar extending from a corner of a room. As clearly shown in Fig. 9, when the angle desired is a right angle, it is only necessary to'cut' two shells, such as the shells 92. and 93 to form an angle of forty-five degrees at 94 with the longitudinally extending sides of the-shells when such shells 92 and 93 may be connected together as indicated in Fig. 9. The reflecting strips 95, 96 and 91, 98 will of course similarly be cut to cooperate with one another to form the right angular configuration shown in Fig. 9.

In theembodiment shown in Fig. 10, advantage is taken of this channeled or trough shaped shell to produce the annulus 99. The annulus 99 shown in Fig. 10 is illustratedas secured to three ceiling brackets I00, HH and I02. The lower end portion I03 of the annulus 99 is similar to the ledge formation of the section It illustrated in Fig. 4. Here the outer faces of the annulus 99 above the portion I03 is illustrated as provided with a raised ornamentation I04 resem-' bling a garland, see Fig. 11.

In the embodiment illustrated in Fig. 12, an annulus I05 composed of the channeled or trough shaped shell, such as the shell 53 of Fig. 6 is shown secured to a plurality of arms I06, I01 and I08 of a standard I09; In this case, it is of course obvious that there'flecting rim or strip II 0 at to one another at their ends H3 and H4 as indicated.

In the embodiment illustrated in Fig. 14, it is illustrated how advantage may be taken of a half ofa trough shaped shell, such as the shell I I5 which is longer in a horizontal direction than it is wide in a vertical direction, to encircle a pillar I 56 constituting a structural or building ele ment. In this embodiment the shell I I5 has the edges of the lower circular wall portion H8 engaging the cylindrical surface or face of the pillar II6 to form a closed bottom continuing into a lateral cone shaped wall poi ion I53 having shoulders formed thereon ornamentally arranged to define a desired design when intercepting reflected light rays from the reflecting rim or strip I similar to the reflectors or strips and 33 of Fig. 3 which intercept light rays from a light source, such as the lamp IZI and reflect such light rays as indirect light rays onto said shoulders.

In the embodiment illustrated in Fig. 15, there is illustrated how advantage is taken of a half of a channeled shell to produce the generic effect here desired to be produced when a straight shell, such as the channel shaped shell secured along the side of a wall. In the present instance, the shell I22 has an inner wall portion connected to the building wall I25, lower wall portion I25 secured to the shoulder or ledge HES constituting a portion of the .iir." ll 52:? and an outwardly flaring curved wall portion I 2'! having an outer face provided with shoulders ornamentally arranged to inter ept light rays reflected by the reflector or strip 23 which is supported along the outer edge of the wall portion I 21 and which intercepts direct light rays from a light source between the wall portions I23 and I21, such as the lamp I25.

In the embodiment illustrated in Fig. 15, it is illustrated how advantage may be taken of the trough shaped shell typified by shell of Fig. 6 to produce a lighting :ture having a plurality of reflecting strips combined with a plurality of outer shells whereby cuter faces of the shells are illuminated by reflected light rays reflected by the reflecting strips of direct light rays produced by a light source disposed within the shells.

In this embodiment, the channel shaped main shell I31 comprises two wells ltl and I32, in the present instance merging into one another at their lower end I33. Here too, the walls ISI and I32 are shown as having secured to their outer faces ornamental or decorative shoulder forming material, such as the portions I38, I31 and I38 which have shoulders in the path of the light rays reflected by the reflecting strips I39 and Hill which receive direct light from a source of light within the trough formed by the shell I), one lamp MI here being shown.

The fixture here shown is illustrative of a ceil ing fixture in which advantage is taken of the brackets for the lamps for support, the lamp MI as an instance being secured to the socket I42 and mounted in the socket cover I53 connected to the ceiling, not shown, and the socket cover I43 is connected to the brackets M4 by any suitable means, such as the flexible chains I45. The brackets S it are in the present instance connected to the blocks 245 which are slotted to receivethe outer edges or the walls HI and I32 and otherwise conformed snugly to fit in the channeled strips I39 and i 38.

In the present instance, the strips I39 and I43 are shown as integral with the outwardly flaring trough forming walls hill and it? extending outwardly and upwardly from said strips I39 and 548.

The outer faces of the walls M3 and I 11 are also provided with an ornamental covering substance, such as the portions I lll and I49 which have shoulders to intercept light rays deflected he inner faces oi": the reflecting strips I55 and lfil which receive and intercept direct light rays from the lamp I and reflect them as indirect light rays onto the outer faces and ornamental portions of the walls M6 and it? as well as parts of the shell Iiiii.

The reflecting strips I58 and. Iii are supported place by being mounted on blocks I52 preferably composed of some translucent material, such as Cate-11in. These blocks conformed to snugly fit into the channels of the channeled strips I553 and I51. These blocks I52 are furthermore slotted to l'uinilt' the outer edges of the walls I46 and I li'.

It is obvious that various changes and modifications may be made to the details of construction without departing from the general spirit of the invention as set forth in the appended claim.

I claim:

to form a closed I r to to; :1 a long narrow trough w AIL; oi the pillar, a plurality of lamps in the trough and out of view rem the outside of said shell, reflecting in 2:; supported on the of the shell and positioned outwardly from the outer edge thereof to receive ar' intercept direct Ii ays from lair-ADS and root them as indirect light rays onto the outer of said shell.
